Drilling is one  of the most important engineering  majors .The   drilling engineer needs to know  several clear information about the nature  of the biologic  configuration of the oil reservoir and its  specifications  (thickness, porosity, layer, depth, permeability, tank pressure and the factors that affected on it) before he starts  drilling, depending on the need to select the appropriate method in drilling and the use of appropriate equipment to the nature of the rocks and the temperature and the expected  pressure, taking into account the existence of other wells where it doesn’t affect  the function of the drilling process.
